To provide a vehicular pneumatic spring which allows large horizontal displacement and can ensure sufficiently proper buffering performance and further can be improved in durability while using a small pneumatic spring with a small effective diameter to reduce a required setting space.

The vehicular pneumatic spring includes top surface plates 1A, 1B; intermediate members 2A, 2B; and undersurface plates 3A, 3B. A laminate rubber 4A, 4B made by stacking alternatively a plurality of ring plates 6a made of a hard material and a plurality of elastic ring plates 6b made of rubber are arranged between the intermediate members 2A, 2B and the undersurface plates 3A, 3B. Besides, between the top surface plates 1A, 1B and the intermediate members 2A, 2B, the pneumatic springs 15A, 15B provided with rubber diaphragms 10A, 10B are vertically arranged in series. The undersurface plate 3A of the upper pneumatic spring 15A and the top surface plate 1B of the lower pneumatic spring 15B are fixed and coupled together.
